CLEVIS FOR REVERSIBLE PLOWS.

SPECIFICATION forming part of Letters Patent No. 294,431, dated March 4, 1884;.

Q A Application filed December 28, 1883. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS A. Bhnnows'a citizen of the United States, residing at Oastleton, in the county of Rutland and State of Vermont, have invented certain new and useful Improvements in Olevises for Reversible Plows; and I do hereby declare that the fol- View of a plow embodying my invention. Fig.

2 is a detail View, in perspective, of the device for holding the lever-rod in position; Fig. 3, a similar view of the clevis, and Fig. at a detail view of the inner portion of the lever-r0d.

The present invention has relation to that class of plows provided with an adjustable clevis and a rod for operating it.

The object of the invention is to improve the means for controlling the adj ustability of the clevis, whereby the operation is rendered more simple and effective, and the construc tion of the device enabling it to be manufactured at a much less cost than heretofore, and more readily attached and applied to the plow. These objects I attain by the construction substantially as shown and described and hereinafter claimed.

In the accompanying drawings, A represents the plow, and B O the plow beam and handles, respectively, which are all of the usual construction, and form no part of my invention. The clevis D may be any of the usual forms, as I do not wish to be understood as confining myself to the construction shown, and is pivoted in the ordinary manner to the beam B. The clevis D is provided with a laterally-extending arm, a, preferably cast with said clevis.

To the extremity of the arm a is suitably connected one end of a lever-rod, E, of sufficient length to extend back to the plow-handles, by which the clevis is operated or turned to either side to govern the furrow-slice. The rod E, near its inner end, is flattened a portion of its length, to form a plate, I), in which is made a series of perforations, c, the extremity of said rod in the rear of the plate being formed into a suitable handle of any de-v I d, for the inner extremity of the rod E. Thehorizontal portion of the angle-plate F is provided with an elongated slot, 6, through which .passes a pin, G, said pinbeing adjustable in a direction crosswise of the plate, and held at the point of adjustment by suitable jam-nutsone above and the other below the plate-said nuts engaging with the screw-threads on the shank of the pin. Any suitable means, however, may be employed for rendering the pin adjustable and holding itwhere adjusted; but

the construction shown is most preferred. The pin G enters one of the perforations or holes 0, so as to hold the rod E stationary after properly adjusting the .clevis D.

Between the end of the pin G and the guard d is left a sufficient space for lifting the rod E above the end of the pin, to disengage it therewith when it is desired to operate the rod for moving the clevis to either the right or left. The object of this adjustment of the clevis is to accommodate the Width of furrow to the plowman, and is especially adapted to reversible or swivel plows.

Having now fully described my invention,
